The prominent Azharite scholar Sheikh `Abdul-Majeed Subh, states the following: “Indeed, there is nothing wrong that a Muslim makes a promise to someone who is dead as long as that promise doesn’t entail any disobedience and the promise itself is in something permissible. However, a Muslim is not permitted to call upon the dead or to think that they can incur interests to one or ward off harm from him. All in all, such promises are not necessary to fulfill in case one is not able to achieve them.”
